摘　　要：根据交流传动电力机车的传动特点，对牵引变压器的工作状态进行了分析，指出交流电力机车牵引变压器设计时应考虑的几个问题——牵引绕组的短路阻抗，电流的高次谐波，网压波动可能引起的过激磁以及直流磁化等，同时给出了相应的解决方法。In view of the drive characteristic of AC drive electric locomotive, the author analyzes the operation mode of the traction transformer and points out several issues one should take into account when design a traction transformer for AC drive electric locomotive:short circuit impedance of traction winding, ultra harmonics of current as well as over magnetic density and DC bias magnetization due to net voltage fluctuation, etc. Also relevant solutions are given.
